摘　　要：为了解滏阳河邯郸段流域重金属污染和分布特征,采集了滏阳河地表水23个水样,分析了8种金属元素(As、Cr、Cu、Ni、Se、Co、Zn、Al)的空间分布特征,结合流域周边环境特征分析了各金属元素的来源,利用内梅罗综合污染指数对重金属污染状况进行了评价。结果表明:滏阳河地表水金属浓度平均值按大小顺序依次为Cr(6.34μg/L)、Se(5.22μg/L)、Al(4.98μg/L)、Ni(2.26μg/L)、Zn(2.20μg/L)、As(1.86μg/L)、Cu(1.61μg/L)、Co(0.20μg/L);按变异系数C_(V)值大小顺序依次为Al(132%)、Cr(84%)、Zn(70%)、Se(54%)、Co(52%)、As(42%)、Cu(45%)、Ni(25%);通过内梅罗综合污染指数计算,滏阳河地表水P_(综)为0.92,重金属污染程度达到轻微污染水平,主要潜在贡献因子为Ni;克里金插值法表明,Co、Cr、Ni和Se在峰峰矿区有含量较高的表现;主成分分析表明,Ni、Se、Co、Zn来源于生活污水的排放,Al和Cr为陶瓷业等工厂生产过程中产生的工业污染。In order to understand the pollution and distribution characteristics of heavy metals in the Handan section of the Fuyang River basin,23 surface water samples of the Fuyang River were collected.The spatial distribution characteristics of 8 metal elements(As,Cr,Cu,Ni,Se,Co,Zn and Al)were analyzed.Combined with the surrounding environmental characteristics,the sources of each metal element were analyzed.The pollution status of heavy metals was evaluated by Nemero comprehensive pollution index method.The results showed that the average concentrations of these eight heavy metals in surface water of Fuyang River ranked from high to low were Cr(6.34 μg/L),Se(5.22 μg/L),Al(4.98 μg/L),Ni(2.26 μg/L),Zn(2.20 μg/L),As(1.86 μg/L),Cu(1.61 μg/L),Co(0.20μg/L).The coefficients of variation(C_(V)) ranked from high to low were Al( 132%),Cr( 84%),Zn(70%),Se(54%),Co(52%),As(42%),Cu(45%) and Ni(25%).By calculating the Nemero comprehensive pollution index,the comprehensive pollution index of surface water in Fuyang River was 0.92 which belongs to the slight pollution level.The main potential contribution factor was Ni.The Kriging interpolation method showed that the contents of Co,Cr,Ni and Se were high in the Fengfeng mining area.The principal component analysis showed that Ni,Se,Co and Zn came from the discharge of domestic sewage,and Al and Cr came from the industrial pollution generated in factories such as ceramic industry.
